Crushing And Grinding Calculations Part 1

- Test methods for characterizing ore comminution behavior ...

crushing steps and different kind of crushers have been developed for different purposes. The size reduction ration is commonly between 5 and 10 in crushing stages, i.e. if the starting size is 1 meter in two-three stages the material can be crushed down to 1 mm particle size. Crushing is followed by grinding and it is quite common to use ...

The desired particle size of determines the number of stages of crushing (primary, secondary and tertiary) and the type of machine to be used. The quantity of material entering the crusher determines the size of the machine selected. The type of crushing or grinding method also impacts the way in which the rock is broken during crushing or ...
